EDF

Associated Team (University of Delaware,USA)

The collaboration with David Colton, Fioralba Cakoni and Peter Monk from the university of Delaware focuses on the development of non standard qualitative-methods for inverse scattering problems. An INRIA associated team between DeFI and the mathematical department of the univercity of Delaware has been created in 2008

Academic Collaborations

University of Goettingen (Germany)

The well established and ongoing collaboration with Rainer Kress from the university of Goettingen focuses on iterative methods of Newton type or decomposition methods to solve imaging problems. Our recent work is dedicated to the use of conformal mapping in electrical impedance tomography.

Ecole Nationale des Ingénieurs de Tunis (Tunisia)

In collaboration with A. Ben-Abda and F. Ben Hassen, H. Haddar supervises the PhD work of R. Mdimagh on inverse source problems (with applications to the localization epileptic centers) and the PhD work of Y. Boukari on inverse crack problems (with application to non destructive evaluation of structures). H. Haddar is also an active member of the associated team ENEE (ENcéphalographie-Epidémiologie-Electronique) between INRIA and the LAMSIN.
Since 2008, a Stic project DGRST(Tunisie)/INRIA
Méthodes innovantes en imagerie et en contrôle non destructif des structures between the DeFI team and the LAMSIN has been created and serves with the ENEE team as a financial support for our common PhD students.

CERFACS (France)

The collaboration with CERFACS (with F. Collino and M'B Fares) focuses on large scale 3-D numerical experiments that simulate inverse electromagnetic scattering problems. Two published articles acknowledge this ongoing collaboration, where currently we explore the case of anisotropic media. The CINES computer resources have been used to simulate synthetic data and perform inversion experiments. We started in 2008 a new project on reduced point-sources models for scattering and inverse problems at high frequencies.

Electrical and Electronics Engineering Faculty (Turkey)

Active collaboration has been established between the electromagnetics research group of I. Akduman and the DeFI team after hiring O. Ozdemir (Post-Doc 2007/2008). One of the main goals of this collaboration is the use of generalized impedance boundary conditions for buried objects imaging and for coatings non destructive testing (a common project has been submitted to the Turkish National Science Foundation in 2008).
